TELEPHONE BOOTH Filed May'sl, 1955 2 sheets-sheet 2 Patented Jan. 21, 1936 UNITED STATES PATENT OFFICE TELEPHONE BOOTH Percival H. Sherron, Jamaica, N. Y. Application May 31, 1933, Serial No. 673,627

13 Claims. (Cl. 20-19) This invention relates to a telephone booth and specically to a booth of the type described and claimed in my application, Serial No. 641,592, led November '7, 1932.

In said application there is described a telephone booth of circular or polygonal cross section provided with a door which slides in an arc to close or open the entrance. It is one object of the present invention to provide an improved means for supporting and guiding a door of this characterV whereby it may move with a maximum ease. l

It is a further object of the present invention to provide means for controlling a light and/or a fan in such booth whereby, when the door is closed, the booth will be illuminated and when the door is open the light will be out.

Other objects of the invention relating to details of construction will become apparent from the following descriptionread in conjunction with the accompanying drawings in which:

Fig. 1 is an elevation of a telephone booth embodying the invention;

Fig. 2 is a vertical section through the same showing the support for the door;

Fig. 3 is a sectional view showing a modied support for the door;

Fig. 4 is a fragmentary elevation partly in section showing the construction of Fig. 3; and

Fig. 5 is a perspective view illustrating a suitable means for guiding the lower portion of the door.

The booth 2 in which is mounted the telephone 4 may be formed as described in my prior application, preferably including a soundproof wall structure indicated at 6. An opening in the side of this booth is arranged to be covered by a door 8 when the telephone is being used, the door being adapted to slide in an arcuate path to open or close the opening as desired. This door is provided with the usual glass window indicated at I0. At its upper end it is provided with bracket members I4 supporting rollers I2 which in the modification of Fig. 2 have their axes inclined upwardly and outwardly in radial planes, the rollers I2 being grooved to engage the edges of conical tracks I6 which extend inwardly so that at any point they will support the rollers as indicated in Fig. 2 extending substantially at a right angle to the roller axis. In the construction illustrated in Fig. 2 the track I6 may be carried by the ceiling structure indicated at I 8, there being provided in this structure an arcuate groove indicated at 20 for the reception of supporting rollers I2.

A switch 22 carried by the ceiling is provided with a forked arm 24 which in one position is arranged to control the switch to close the circuit through a light 26 and in another position is arranged to open such circuit. formed as to be engaged by a roller so as to be moved to one or the other of its positions above mentioned and then permit the rollers to pass. The arrangement is such that as the roller which actuates the `switch engages it as the door is being opened, the circuit will be broken and will remain broken as the door is moved to its fully opened position. The switch will not again close until the door is substantially closed. The light is lit whenever someone is within the booth with the doorclosed.

By the roller supporting arrangement as shown not only is the center of gravity of the door located substantially below the track I6 but the movement is much easier in view-of the conical shape of the track and the inclination of the rollers I2. The parts are so positioned that normally the door` will not tightly engage the grooved member indicated at 28 so that free movement is provided. Instead of providing a grooved member such as 28 to receive the door, the door may be grooved to embrace an arcuate flange.

The modication shown in Figs. 3 and 4 illustrates an alternative arrangement of the rollers in this case indicated at 32 and supported by brackets indicated at 30. The rollers in this case have their axes extending upwardly and inwardly of the booth, the track 34 being correspondingly disposed so as to provide a downwardly convergent cone. 'Ihe switch 36 in this case is preferably supported by the side wall of the booth and has a fork 38 properly located to engage one of the rollers to provide the type of action described above in connection with the rst modication. Both door supporting arrangements provide for a minimum resistance to movement in the operation of the door.

It will be clear that numerous variations may be made in the embodiment of the invention without departing from the scope thereof, as defined in the following claims.

What I claim and desire to protect by Letters Patent is:

1. A telephone booth provided with a vertical door moving in an arcuate path, a curved track and rollers running on said track for supporting said door, said rollers having their axes inclined to the horizontal.

2. A telephone booth provided with a vertical door moving in an arcuate path, a curved track The fork 24 is so 5 to the horizontal, said track being inclined to correspond with said rollers.

5. A telephone booth provided with a vertical door moving in an arcuate path,a curved track and rollers running on said track forsupporting said door, said rollers having their axes inclined upwardly and outwardly, said track being inclined to correspond with said rollers.

6. A telephone booth provided with a vertical door moving in an arcuate path, a curved track and rollers running on said track for supporting said door, said rollers having their axes inclined upwardly and inwardly, said track being inclined to correspond with said rollers.

7. A telephone booth provided with a vertical door moving in an arcuate path, a curved track and rollers running on said track for supporting said door, said rollers having their axes inclined to the horizontal, and a member providing an arcuate groove for the reception and guidance of the lower end of the door.

8. A telephone booth provided with a door movable in an arcuate path, electrically controlled means within the booth, and a switch for controlling said means arranged to be operated by movements of said door, said switch including a member engageable by a roller supporting the door whereby the switch is opened and closed by movements of the door to its opened and closed positions.

9. A telephone booth provided with a door movable in an arcuate path, electrically controlled means within the booth, and a switch for controlling said means arranged to be operated by movements of said door., said switch including a forked member engageable by a roller supporting the door whereby the switch is opened and closed by movements of the door to its opened and closed positions, said fork permitting further movements of the roller as it is moved to its extreme positions.

10. A structure provided with a member moving inl an arcuate path, a curved track and rollers on said track for supporting said member, said rollers having their axes inclined with respect to a plane normal to the. axis of, movement of said member.

l1. A structure provided with a member moving in an arcuate path, a curved track and rollers on said track for supporting said member, said rollers having their axes inclinedwith respect to a plane normal to the axisk of movement of said member, and said track being inclined to correspond with said rollers.

, 12. A structure provided with a closure member moving in an arcuate path, a curved track and rollers on said track for supporting said member, said rollers having their axes inclined with respect to a plane normal to the axis of movement of said member.

13. A structure provided with a closure member moving in an arcuate path, a curved track and rollers on said track for supporting said member, said rollers having their axes inclined with respect to a plane normal to the axis of movement of said member, and said track being inclined to correspond with said rollers.
